BOARD-RU LE.

SPECIFICATION forming part of Letters Patent No. 469,363, dated February 23, 1892.

Application filed March 30, 1891. $erial No. 887,041. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE BENJAMIN HOWLAND, a citizen of the United States, residing at Pontiac, in the county of Livingston and State of Illinois, have invented a new and useful Register for Board-Rules, of which the following is a specification.

My invention relates to improvements in board-rules used in measuring lumber; and

the object of my invention is to provide a registering device whereby the person measuring lumber is enabled to conveniently register each hundred feet as measured, thereby obviating the necessity of keeping the numr 5 ber in mind or of resorting to the usual and more inconvenient methods of recording the same. This I accomplish by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a handle for a board-rule, showing the registering device applied thereto, which may be attached to a rule in any convenient way. Fig. 2 is a bottom view of the device; Fig. 3, same view 2 5 with the frame G removed in order to display more clearly the Working parts. Fig. 4 is an inverted vertical section. Fig. 5 is a per- Fig.

spective of under side of the dial-plate. 6 is a top view of the dial-plate.

Similar letters refer to similar parts through- 0 out the several views.

By grasping the shaft at F and turning it to the left, the pawl O striking a tooth of the flange B, the dial-plate is made to rotate sufficiently to bring the next figure on the plate 3 5 directly under the aperture in the cap H; The stud K in opening J limits the movement of the shaft A, and the spring or pawl E prevents any backward movement of the plate. Spring D brings the shaft, with pawl 0, back to its former position ready for a repetition of the movement Whenever desired.

It will be noticed that the pawl O and spring D are formed of one piece of metal, (usually spring-wire,) which passes through and around the shaft A, to which it is firmly attached by means of a key.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a board-rule, the combination, with han- 5o dle J, of a registering device consisting of a dial-plate M, with its serrated flange B, pawls O and E, spring D, stop K, cap H, and shaft A, substantially as set forth.
